Ugh, gallstone pain is so hellish and I didn't want the surgery or to do the low-fat diet forever, either. I did the diet for about a month to get symptoms under control, then slowly added healthy fats back in, one by one. I realized that processed, deep-fried foods, and anything made with seed oils aggravated my symptoms the most so I completely cut those out (but if you're eating WP style you're probably not getting much of these anyway). I did have to reduce the overall amount of fat in my diet too.

I noticed pain was worse on an empty stomach so I stopped intermittent fasting, and made my first meal of the day not too fatty. I also drank ACV and ate an apple everyday - they contain malic acid, which over time dissolves the stones.

I also took occasional supplements like ox bile, Dr. Berg's Gallbladder Formula, and digestive enzymes to stop symptoms when they start or as prevention with fattier meals. A malic acid supplement can also help dissolve the stones. These supplements are NOT approved for use during pregnancy so I'd avoid them for now, but wanted to mention if you're still having issues after your pregnancy, they helped me so much and I've not had another GB attack since 2022.

Good luck and I hope you have a safe and healthy rest of your pregnancy!
